Security of Vehicular Ad-hoc NETworks (VANETs) has been a major research area in both academia and industry. Reducing cost of computation, effective consumption of limited resources and providing uncompromised security has always been a challenge in vehicular communications. Security establishment with no certificates and/or certificate revocation gives lesser signature overhead. A novel approach using ID-based cryptosystem and proxy blind signature based on Elliptic Curve Discrete Logarithm Problem (ECDLP) over VANETs has been proposed. The security of the proposed scheme is dependent on ECDLP which takes full exponential time.
